WebApr 12, 2024 · By LD-HW, further fluorescent imaging on oleic acid-treated cell models showed that the fluorescence intensity in cells was mainly related to the size of LDs. Finally, the visualization of lipid droplets in the NAFLD mice model was achieved, and the fatty liver was discerned from the normal organs in living mice by LD-HW ( Figure 10 B–E). WebDec 1, 2024 · The spectrum further changes with a decrease in the absorbance at 327 nm with an isosbestic point at 454 nm, finally exhibiting a peak at 429 nm. As shown by the inset, the time profile for the decrease in the 327 nm absorbance is consistent with the profile for the fluorescence intensity increase (inset of Figure 3a).
